  • Publication number: 20180360329
    Abstract: A physiological signal sensor to measure life signs includes at least one first and one second Doppler detectors, at least one first amplification filter, at least one second amplification filter, a processor, and a transceiver. Data from the physiological signal sensor is sent to the first and second Doppler detectors to detect first and second physiological signals from different locations on a living body. The two physiological signals are sent to the first and second amplification filters and amplified and filtered, and converted to obtain a first and second digital sensed signal. Digital signal processing is carried out on the digital sensed signals to obtain first and second physiological information which are outputted via the transceiver.

  • Publication number: 20180325219
    Abstract: An apparatus for buffing a shoe part includes a housing adapted to be articulated around at least a portion of the footwear part. A rotating spindle is positioned in the housing and has a buffing surface for engagement with the footwear part. A carriage is slideably connected to the housing and holds the spindle such that the buffing surface can be moved closer to and further away from the footwear part. An actuator is in the housing and in contact with the carriage. The actuator applies force to the carriage to increase the force of the buffing surface onto the footwear part. A biasing member is in the housing and in contact with the carriage. The biasing member exerts force onto the carriage in a direction opposite the force exerted by the actuator.
